MEANS FOR TRANSFER-RING WARE TO LEE-RS.

Application filed March 15, 1923. Serial No. 625,178.

To all whom it may concern:

Be it known that I, RICHARD LA FRANCE, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented new and useful Improvements in Means for Transferring Ware 7 to Leers,

the articles are carried of which the following is a specification.

My invention relates to apparatus for transferring bottles or other lass ware to an annealing oven or leer. ne form of apparatus for this urpose in commercial use at the present ay, comprises an end less belt or conveyor, traveling transversely through the end of the leer and on which within the leer. A pusher device is o erated periodically to the belt onto the usual articles are rapidly supplied in this manner' to the leer, difliculty is sometimes experienced on account of the bottles or other the abovedifiiculty by ware piling up during the operation of the pusher device or interfering with the operation of themechanism.

An object of my invention is to overcome fproviding means for rom the carrying-in transferring the ware belt to the leer conveyor without interwith the continuous rupting or interfering advance of the incoming articles.

A further aim of'the' invention is to pro 'vide means of this character which is simple in construction and free from mechanical complications.

Other objects of pear hereinafter. v In the accompanying drawmgs: Figure I-is apart apparatus constructed in accordance with my invention.

.Fi re 2 is. asectional line I-II on Figure 1.

7 The annealing oven or leer 5 is provided with the usual leer conveyor 6 which runs on rolls 7 and by which bottles 8 orother glass articles are carried slowly" through The endless carrying-in belt or conveyor 9 extends transversely through the the invention will apelevation at the .leer adjacent the receiving end of the leer,

said belt being mounted on pulleys 10 and 11, the latter driven by a continuously running motor 12. The upper and lower leads of the belt 9 extend respectively through openings 13 and 14 inthe side walls of the trol the valves 32,

leer. The bottles 8', or other articles to be 3 from which they slide onto traveling belt 9 at a point outside of the leer and are carried by the belt into the leer.

A transfer device or pusher for transferring the bottles to the leer conveyor, comprises a pusher bar 16 within the leer extending lengthwise of the belt 9. The pusher bar is carried by rods 17 extending rearwardly through .openin s 18 in the end wall of the leer and. ,coninected at their rear ends to rock arms 19 and 20, fixed to and projecting upwardly from a rock shaft 21. wardly beyond the rods 17 and is connected through a link 22 to the piston rod 23 and piston 24 of an air motor 25.. Y

The pusher rods 17 are sup orted inter-- mediate their ends on grooves pulleys 28 carried on rock arms 26, fixed toa rock shaft 27. An arm 29 fixed to and extending upwardly from the rock shaft 27 is con- The rocl; arm- 20 extends upnectpd at its upper end to air motor 30.

the supply of air from the and 38 control the supply to pipes x 39 and 40, leading respectively to the ends The operation is as follows: The bottles I or other articles 8 are delivered in rapidsucsectional plan view of.

cession to the continuously running carrying-in belt 9, so that a continuous row 'of such articles is being carried into the leer. The continuously running motor 12 which drives the carrying-in belt also operates the.

pnto an inclined ment oft e pusher bar,'the pulleys, 28 are ushing or wiping a 7' y slide onto the tcr operates to retract the the movement of the "crab e to efi ct periodic in their lowered position (Fig. 2). As the pusher bar completes, or is completing, its forward movement, the motor 30 is brought into operation to lift said bar from the broken line position 0 (Fig. 2) to the broken line position 7. This operation of the motor 30 is effected by means of the cam 0 opening the valve 32 and admitting air to the forward end ofthe motor. As soon as the pusher bar reaches the elevated position f, the valve 37 operates to supply air to the forward ead of the motor 25 so that the latpusher bar while it is held in its elevated position. The valve 1) now operates to supply air to the motor 30 for moving the rock arm' 29 forward and lowering the pulleys 28, so that the pusher rods are lowered to their initial position.

It will be observed that the pusher bar 16 when in its forward position, is beyond the path of'the incoming row of bottles, so

that it does not interfere with the continuous advance of the bottles. Also, as the usher bar is held elevated above, the pathof the bottles while the bar is being retracted, there is no interference at this time. It is to be noted further that the, pusher rods 17, after their forward movement, are lifted abovethe path of the bottles before there is opportunity for any interference with the incommg bottles. Moreover, the forward movement of the pusher bar takes place with sufficient rapidity to prevent any substantial interference with; or interruption of,

bottles into the leer.

Modifications may be resorted to within the spirit and scope of my invention.

What I claim is:

. 1. The combination of a horizontally travelin conve or a pusher extending lengthwise thereof, a

motor having connections with said pusher and operable to move it,

back and forth over the conveyor, a second motor, connections between said second mo- .tor and the pusher for lifting and lowering the usher,'and controlling mechanism opmotors in a predetermined time relation.

operations of the,

with said pusher and operable to move it back and forth over the conveyor, a second motor, connections between said second motor and the pusher for lifting and lowering the pusher, valves controlling the motors, and means for'actuating the valves in such timed relation that the pusher is first moved forward, then lifted, then retracted and then loweied.

3. The combination of a leer, an endless belt conveyor extending transversely through the leer, a continuously running motor to drive said belt, a pusher bar extending lengthwise of the conveyor, means comprising motors for moving the pusher back and forth and for lifting and lowering it, valves controlling said last mentioned motors and thereby controlling said movements of the pusher, and cams operated by said first mentioned motor for controlling the valves.

4. The combination of a leer, a conveyor extending transversely through the leer, a pusher bar extending lengthwise of the conveyor, rods carrying said bar and extending rearwardly therefrom, a rock shaft, rock arms extending upwardly from the rock shaft and connected to the rear ends of said rods, a motor having connections for rocking said shaft and thereby moving said rods and pusher bar second motor, operating connections between said second motor and said rods for swinging the latter up and down about their points of connection with said rock arms and thereby lifting'and lowering the pusher bar, and automatic means for effecting periodic operations of said motors in a predetermined forwardly and rearwardly, a r Y time relation such that said bar is periodi cally moved forward overwthe conveyor lifted, moved rearwardly and then lowered.

Signed at Toledo, in the county of Lucas and State of Ohio, this 10th day of March, 1923. a
